The invention relates to a device and a method for producing an operating medium for a motor vehicle, especially for use in the exhaust gas post-treatment of the motor vehicle. According to said method, an operating medium is produced from an initial product and air using a catalyst device. Said initial product is heated and mixed with air and the heated mixture of initial product/air is fed to the catalyst device. A part of the initial product is converted to the gaseous phase by means of a preheating element and is entrained by a stream of air when leaving the preheating element, said stream of air leading to a combustion chamber. The method allows to efficiently produce an operating medium, especially a reducing agent for regenerating NOstorage catalysts.

A dosing mechanism for fuels, particularly for the input into a chemical reformer to obtain hydrogen, has a metering-in device for metering fuel into a supply line, which opens out at at least one dosing aperture into a transporting line transporting a tempered material flow. A holding device for accommodating the metering-in device has an insulating body which thermally insulates the metering-in device from the transporting line that transports the tempered material flow.

Dosing device

An atomization system for fuels, particularly for charging a chemical reformer for obtaining hydrogen, features at least one metering device, accommodated in a supporting device, for metering fuel into a temperature-adjusted substance stream, which introduces the fuel directly into the temperature-adjusted substance stream without the interpolation of a supply line.

Atomizer device

A device and a method are proposed for the introduction of a processing agent downstream of the engine, in particular a fuel, into the exhaust-gas stream of an internal combustion engine, in which a gas discharge for boosting an at least partial of the supplied processing agent is supported.

An arrangement for supplying liquid media to consumers of a fuel cell system having a feed pump is suggested which is less complex compared to known arrangements. This is achieved in that controllable metering valves () are provided between the feed pump () and the respective consumers.

Atomizing nozzle for introducing a gas/liquid mixture into a chemical reformer to produce hydrogen, having at least one gas supply line () for a gas stream (), at least one liquid supply line () and at least one outlet () for the atomized gas/liquid mixture as well as a first chamber () into which the liquid supply line () empties, with the chamber () having a chamber wall () that forms a lip () at the outlet end, on both sides of which a separate gas flow () is supplied.

An apparatus for delivering at least two liquid media to consumers of a fuel cell system, with a feed pump is made less complicated than known apparatuses in that at least one pressure transmission unit between the at least two media is provided with at least one pressure transmission element, which has at least two pressure faces for pressure imposition that communicate with the liquid media.

The invention relates to an apparatus for dividing an entering gas flow into two split flows, each of which flows through a branch of a line system. A control element is provided, which executes a control motion about a shaft between a first position and a second position. The entering gas flow is divided continuously, by means of the adjustable control element, at a volumetric flow ratio, and at the same time the control element allocates a medium to be metered, whose infeed point is associated with the control element, to the split flows at a different ratio V.

Control element for the simultaneous control of gaseous streams

A metering unit for metering liquid and/or gaseous educts by means of a feed pump for a fuel cell system, including at least one lead line for delivering an educt flow, at least one control piston, and a differential pressure valve for regulating the educt flow; the differential pressure valve has a regulatable throttling cross section, which is variable automatically, as a function of a flow pressure dictated by the control piston, in order to regulate the educt flow. The lead line leads to the control piston, and between the control piston and the differential pressure valve a first and a second connecting line are provided.

In a method and device for selective catalytic NOx reduction in oxygen-containing exhaust gases using ammonia and a reduction catalyst, gaseous ammonia is made available by heating a solid storage medium in a container. The method and device are suitable for use in motor vehicles in particular.

Method and device for selective catalytic NOx reduction

A device for re-treating exhaust gases of an internal combustion engine is proposed, in which to promote the efficiency of a downstream reducing catalytic converter, fuel is metered via a metering valve and introduced into the exhaust system via an evaporator device. A metal sheath is provided with a sheathed glow-plug element that is used as the evaporator device and via a flow opening on a face end introduces an evaporated reducing agent into the exhaust gas stream.
